.lecting cup, and to permit trucks to pass thereover.

' The nipple 24 has lugs 29.extending from the inner wall thereof, which lugs support a valve 30, and said valve-is adapted to be elevated by air pressure to, close the nipple 23 when air is admitted tothe tank 25 to expel the liquid therefrom, the said valve 30 unseating by gravity when the air pressure within the tank is removed, and restingon the lugs 29, in which position water may pass from the collecting cup around the periphery of the valve to the interior of .the tank 25.

- The tank has a water discharge pipe 31,.

the inner end of which may be engaged by the valve 32, which valve is applied to the interior of the tank 25 and supported by the hinge 33 so that said valve may swing freely within the tank. As shown in Fig. 6 the valve has a filling 34which is preferably cork or other light material that will float,

or the said valve may be hollowand when air-tight it would have a tendency to float when water reaches the interior fthe tank. It is apparent from an inspection of Fig. 3 that the float valve will unseat and assume the position shown in full lines in said figure when water is in the tank, whereas when water is expelled from the tank the said valve will seat on the end of the pipe 31 and close the opening to prevent the es-. cape of air which is used for expelling the water. If the float valve were not present.

to close the end of the pipe 31 air would escape and the operation of the air brake system might thereby be impaired. The normal position oft-he valve 48 when water is collecting inthe tank 25 is one at right anglesto that shown in Fig.4. It'is shown in Figs. 10 and 11 that the pipe 31 extends upwardly and terminateswith its discharge orifice 35 at the side of the car so that the water forced from the tank is discharged laterally of the car; it being thepurpose of the inventor to have the pressure on the water sutlicient to force the outgoing water clear of the track and road-bed, so thatsaid water will not damage these properties.

The fact that the discharge end is above the 25 I provide each. car with an air pipe 36,

thepipe of each car being a part of a train,

line for the passage ofair; which train line is distinct from the train line for. the air brakes. Each pipe 36 is in communication with the interior of the tank by means of a coupling 37 so that when air is 01 1.the

train line of which the pipes 36 are a part,

air is supplied to the interior of each tank of any ordinary construction, those which are usually used in air brake systemsbeing' adapted for use between the said pipes. The pipes '36 are provided at each end with a valve 38, which maybe closed in the end' of the pipe remote from the pump, all of the other valves in a train line, when the cars are coupled, being open to afford communication from one end of the train to the other.

In the diagrammatic 'view (Fig. 1) I have illustrated the air brake line 39 as parallel with the air' system for discharging the water, and it will be obvious that the installation of the air discharging means will not interfere with the air brake.

The air pump 40 is connected to adouble valve 41 through the pipe 42, and the valve 41 has a short pipe 43' in communication.

with the safety. valve 44. A T coupling 45 is interposed in. the pipe 43 and said T-cou-' pling 45 has a pipe 46 extending from it to communicatewith the valve'41 at the lower end of the casing; Furthermore the casing of the valve 41 has an exhaust pipe 47 conexhaust for the train line. It is shown in Fig. 4 that the port -49'is at right angles to the port 50. 'so that when the valveplug is turned, it alternately opens and closes the pipes accordingto the direction or degree of' movement. ofthe plug, The plugmay be held in place in any appropriate way and it is here shownas provided with a plate 51 bound against the bottom of the case by the nut which nut is threaded on astud 53 depending from the plug. i V 1 The tank 25 is removably' supported inplace by. the'stirrups or straps 54- partially embracing the tank' andv having their ends attached tothe sills of the car by fastenings 55. One head ofthe tank isremovably secured in place at the joint 56. The air'pipe or train line isin communication with'a prcssuregage 57 so that the operatormay supply a uniform and required-pressure for forcing. the water'from the "tank, and obthepressurc within-the train line.-

25: The ends of the pipes 36 have couplings -nectedto it so that when the "valve is operated to close the air supply line,-'.'it will open 7 [the air exhaust pipe-and vice versa. 'The 50 is intended to effect communication between the sections of pipe constituting the icense in the car floor, a collecting cup, means of communication between the cups whereby.

Water from the-first named cups flows into the eollectin cup, a"tank, means of communication between the collecting cup and the tank, a valvein said means adapted to close hy pressure from within the tank, a

discharge pipe for the tank, means for supplying air under pressure to the tank for expelling water therefrom, and a valve for closing the discharge pipe after Water is expelled from the tanln 2. improvements in cars comprisinga car having openings; in its floor, cups in said openings, pipes leading from said cups, a

collecting cup into which the pipes discharge, a tank, means of communication be-v colle ting cup and the tank, a valve for contronin said means of commua nieation, a discharge pipe for the tank terminating at the side of the car and above the lane of the Water in the tank, a valve Within the tank for closing the discharge pipe after water is expelled from the tank, and means for supplying air under pressure to the tank.

3. Improvements in cars comprising a car having openings in its floor, a collecting cup, means of communication between the openings in the floor and the collecting cup, a

tank, means of communication between the collecting cup and the tank, a valve for controlling said means of communication, a discharge pipe for the tank terminating at the side of the car and above the plane of the Water in the tank, a valve within the tank for closing the discharge pipe after water is expellecl from the tank, an air pipe in communication with the tank, and means for supplying air to the pipe.
